S'IANEIQ, first provide asuitable' gear casing 10 that e United States, residing at may be forn'ied of the usual material having tenwick, in the county of Humboldt and one side portion 11 permanently afiixed e invented certain new thereto as shown and the other side portion ements in Transmission- 12 detachably connected as at 13.

The member 33 being slightly longer than the other member 34, is provided with an annular rim or 36 as clearly shown in Fig. 1. An operating rod 37 is mounted to be slidable within the gear casing, carrying adjacent its inner end an adjustable arm 38 as at 39, the latter having: a fork-or ring 40 to operate in the channel between the rim 36 and the body of the gear 32. Consequentlv it will be seen that by properly shifting the rod 37, the gear 32 may be moved so as to bring the club: member 33 thereof and the fingers thereon into mesh with the fingers of the other .clutch member. At its outer end the rod 37 may be provided with an eye 41, as shown in Fig. 1.

A countenshaft d2 has its ends journaled in bearings 43 and 4d that fit into suitable sockets 45 and 46 of the side plates 11 and 12 rospectively, the said counter-shaft carrying a pinion 47 through the medium of a key 48 for co-meshing engagement with the driving pinion 17 A secon pinion 49 is arranged on the counter-shaft 42 through the medium of a key 50, the same being substantially greater in diameter than the pinion 4,7 and designed to mesh with'the car 32 at certain times as will subsequent y a pear.

As before stated, no improv transmission device is preferab y used in conjunction with an automobile or motor driven vehicle having a two speed clutch, namely high and low gear, being specially designed or use in connection with automobiles of the Ford type. When desiring to operate the machine on low speed, the parts having been positioned as shown in Fig. 1 with the fingers 35 of the respective clutch members 33 and 34 in meshing engagemenfito produce a direct connection between the driving shaft 16 and gear shaft 25 the low gear clutch of the car is then operated, and the desired first or low speed is obtained. When desirin to obtain the next or second speed, the sli ing rod 37 is operated so as to shift the gear 39 into co-meshing engagement with the pinion 49 of the counter-shaft which, as is obvious, places the direct connection between the drivinc, alli lft 16 and the gear shaft 25, motion from the drivin shaft being imparted to the gear shaft t rough the instrumentality of the driving iinion 17,.the pinion 47 of the counter-sha hence to the pinion 49 of the counter-shaft and finally to the gear 32 and which is accomplished by actuating the low speed pedal. When desiring the third or direct speed. the operator moves the gear to its first position. as shown in Fig. 1. after vvhich the high gear clutch is thrown into operation so'as.to ci g'cct the desired result. Finally when desiring to attain the highestor fourth speed. the gear 32 is shifted into mesh with the large pinion 49 or the counter shaft as shown in Fig. 2 after. which the high gear clutch is again moved into operation and the highest speed is obtained owing to the high gearing o the two shafts.

From the foregoing it will be noted that I have provided a novel form of transmission that is readily susceptible of application to conventional forms of motors and differential gearings and which is especially susceptible or use in connection with the mechanism of an automobile of the Ford type.' In view of the fact that the advanta and novel features of the device appear to be clearly defined from the foregoing, further detail description is deemed unnecessary.

In reduci find that the cm referred to herein as the most practical and preferred embodiment is the most eflicient, but realizing that certain conditions will nrily vary in concurronco with the adoption of my device, I desire to emphasize the fact that various minor changes in the details of condruction and in the proportion of parts ma be resorted to when required without mcri ing any of tho advantss of my invention as defined in the ap d claims.
